Flow at Criticality

Flow at criticality is the recognition that Mihaly Csikszentmihalyi's conditions for flow—challenge matched to skill, immediate feedback, clear goals—are, when translated into the language of physics, exactly the conditions for maintaining a system at the edge of chaos described by Per Bak's self-organized criticality. Challenge must match skill: too much challenge pushes the cognitive system into the chaotic regime (anxiety, disorientation); too little pushes it into the frozen regime (boredom, disengagement). Immediate feedback is the mechanism by which the system makes continuous micro-adjustments that keep it at the critical point. Clear goals provide the boundary conditions that prevent the system from dissolving into noise. This convergence is not metaphorical. Neural networks self-organize toward the critical point during training; the brain criticality hypothesis holds that human cognition operates most effectively at the same dynamical regime. Flow is not a psychological state that resembles physical criticality.
